Iron Man easily took the #1 spot for the second week in a row as Speed Racer crashed and burned to become the first official flop of the summer. What Happens in Vegas actually managed a #2 debut with $20.2 million, while Speed Racer made only $18.6, or about half of what the studio was praying for. Adding insult to injury, yesterday's estimates incorrectly placed the film at just over $20 million, a little ahead of Vegas. A third place debut is nothing short of disastrous for the $125 million-budgeted flick. The top ten official numbers, in millions:

Also successful is What Happened in Vegas - the chick flick scored a better opening than last week's Made of Honor as well as last month's Forgetting Sarah Marshall. However, competition-wise, the summer is an unforgiving place, so a final total will have to be judged by how well the film holds up next week.

The rest of the top ten simply slid down a few notches, staying in the same order it was in last weekend. In 11th place was David Mamet's Redbelt with $1.0 million, which expanded to a surprisingly wide 1,379 theaters this weekend after one week of limited play, but scored an atrocious $734 per-theater average.
